| 摘 要： | 利用奇异值分解确定了用户信号的个数,并把天线阵接收的数据矩阵映射到信号子空间上,进而在该空间中讨论波束形成问题并导出了多用户波束形成的必要条件,依据此条件将正交化过程引入最小二乘恒模算法并提出了正交化恒模算法。计算机仿真证实了算法的有效性。 |
| 关 键 词： | 盲波束形成 正交化 恒模算法 |

| Abstract: | The number of desired signals is detected by using singular value decomposition. And the array input is transformed into the signal subspace. Orthogonality is derived for the weight vectors in multiple beamforming on this subspace. According to which, an orthogonal constant modulus algorithm is proposed by introducing the orthonormalization procedure into the static least square constant modulus algorithm. The simulation results via computer confirm its validity. |
| Keywords: | blind beamforming orthogonalization constant modulus algorithm |
